if ( !function_exists('library') ) {
    
    function library(string $name, ...$params) {
        $library = '\App\Libraries\\' . ucfirst($name) . 'Library';
        return new $library(...$params);
    }
    
} 


app/Controllers/Home.php

PHP Code:

<?php namespace App\Controllers;

class Home extends BaseController {
    
    public function index() {
        echo library('shop')::displayPrice(25.000) . '<br>';
        echo library('shop')->priceFormat(30.000) . '<br>';
        
        $shop = library('shop');
        echo $shop::displayPrice(40) . '<br>';
        echo $shop->priceFormat(50);
    }

}

PHP Code:

<?php namespace App\Libraries;

class ShopLibrary {
    
    public static function displayPrice($price) {
        return (new self)->priceFormat($price);
    }
    
    public function priceFormat($price) {
        return number_format($price, 2, '.', '');
    }
